UNITED STATES PATENT OFFICE ADJUSTABLE manna FOR EYEGLASSES I William R. iackson, Tucson, Ariz.

Application July 20, 1945, Serial No. 606,143

The present invention relates to new and useful improvements 'in eyeglasses, and more particularly to an adjustable temple by means of which the ear-engaging rear end of the temple may be adjusted to a desired length in accordance with the sides of a head of a person wearing the eyeglasses.

More specifically, the invention embodies the construction of a temple bar formed of two sections telescopically arranged, the front section being connected with the lens frame and the rear section being formed with the ear-engaging member, together with means for holding the sections in longitudinally adjusted position.

An important object of the present invention is to provide an adjustable temple of this character in which none of the working parts provided for the adjustment of the temple protrudes on the outside thereof to mar the beauty of the temple or to cause discomfort to the wearer.

A further object of the invention is to provide a device of this character of simple and practical construction, which is neat and attractive in apview of the longitudinally split sleeve forming theinner section of the temple, and with a portion of the outer section of the temple shown in elevation.

Figure 4 is a similar view showing the sections of the temple ready for assembly.

Figure 5 is a similar view showing the sections of the temple connected to each other. Figure 6 is a transverse sectionalviewtaken 'substantiallyon a line 6-6 of Figure 5.

Figure 7 is a perspective view of the construction for connecting the inner section of the temple to the eyeglass frame.

Referrin now to the drawing in detail, wherein for the purpose of illustration I have disclosed a preferred embodiment of the invention, the-numetal 5 designates an eyeglass frame having an v outwardly projecting lug 6 at its outer edge'fand' also formed with upper and lower, spaced-apart,

' I struction, operation and advantages of the device will be quite apparent to those skilled in the'art.

'pearance, relatively inexpensive to manufacture,

-mediately rearwardly of the lug 6.

1 Claim. (Cl. 88'5 2) outwardly projecting lugs 1 and 8pos-itioned im- A pin 9 extends vertically between the lugs 'I and 8 and 'to which the inner end of the inner temple section II) is pivotally attached, said inner end of the section ill of the temple also having a laterally projecting lug I l at its pivoted inner end adapted to abut the lug 6 of the frame to limit outward swinging movement of the temple.

The inner section In of the temple is constructed in the form of a longitudinally split sleeve which is closed at its pivoted end.

The sleeve l0 forming the inner section of the temple may be constructed of any suitable material, such as light weight metal, plastic, or the like, and is formed with internal lugs [2 at longitudinally spaced intervals by pressing inwardly portions of the material at the outer surface of the sleeve.

The longitudinally split sections of the sleeve may be expanded into an open position, as shown in Figure 4 of the drawing, to receive the outer solid temple section l3 having its inner end formed with notches or grooves l4 adapted to receive the lugs I! of the sleeve to secure the inner and outer sections of the temple in longitudinally adjusted position one within the other, in the manner as illustrated in Figure 5 of the drawing.

The outer end of the section I3 may be curved, as indicated at l5, to form the ear-engaging member.

The inner section ill of the temple is preferably constructed of resilient material to facilitate the expanding thereof to permit adjustment of the outer section is therein, and the outer section l3 may also be rotated in the sleeve iii to move the ear-engaging member l5 inwardly or outwardly against the side of a person's head in accordance with the requirements to provide a comfortable fit for the temple bar against the side of the head. 4

In view of the foregoing description, taken in conjunction with the accompanying drawing. it is believed that a clear understanding of the con- A more detailed description is accordingly deemed unnecessary.

It is to be understood, however, that even 1 though .I have herein shown and described a preferred embodiment of my invention, the same 7 is susceptible: to certain changes fully comprehended by the spirit of the invention as herein described and the scope ofthe appended claim.

A temple for eyeglasses comprising inner and outer telescoping temple sections, the inner one of which comprises a sleeve having a closed end adapted to belattached to said eyeglasses, said sections being endwise slidable relatively tor varying the length of the temple, inwardly pressed lugs on the sleeve spaced apart in longitudinal rows upon opposite sides of the same, and recesses in the outer sections spaced'apart in longitudinal rows upon opposite sides thereof for interlocking with said lugs to oppose endwise sliding of said sections, said sleeve being longitudinally split for spreading apart to provide for endwise 1 sliding of the sections while said lugs and recesses are positioned for interlocking, said lugs and recesses providing for relative rotation of said sections to adjust the angular position of the outer section relative to the inner section while said lugs and recesses are interlocked, said 4 lugs and recesses being constructed and arrange to provide for relative rotation of said sections to break the interlock between the lugs and recesses so that said sections may be easily pulled apart endwise.
